ARTHUR L. MITCHELL, OF PORTLAND, MAINE.

SHOCK-ABSORBER.

To all whom it may concern:

Be it known that I, ARTHUR L. MITCHELL, a citizen of the United States of America, and a resident of Portland, in the county of Cumberland, State of Maine, have invented certain new and useful Improvements in Shock-Absorbers, of which the following is 1 member composed of a socket m provided,

a specification. a

My invention relates to a shock absorber for spring supportedvehicles and it is particularly designed to be used on the socalled Ford automobiles in which the body of the car is supported on leaf springs located directly above the axles although the invention is capable of being otherwise used. I have illustrated my invention by means of the accompanying drawing in Wl'llCh is shown my shock absorber applied to both. the forward and rear axles of the Ford vertically disposed above the axle and a isthe bolster.

ing member adapted to be held beneath the axle. As here shown, this bearing member is in the form'of an elongated plate 0 whichfits beneath the axle, and beneath each'end of the plate 0 there is a plate d extending transversely of the axle and being provided with a central vertical opening. The vertical motion of the plate (Z is guided by a bolt 6 which is securedby its upperend to the-plate c with its lower end extending through the plated and being provided with a nut 'therebeneath. The upward thrust of the spring is relieved by a spiral spring which surroundsd the bolt 5 and is disposed between the plate 03 and-the plate 0. The plate J is connected with the body of the vehicle so that the upward motion of the latter is taken up by the spring. As here of the center, embracing the axle and the Specification of Letters Patent.

spiral spring. A buckle g" isprovide diby which the two parts of the strap are united and by which the device is secured in place. Referring to Fig. 2, 7c represents the houswith a clamping device m for clamping the socket m to the rear axle. Beneath the socket m is the plate 11 having a vertical opening through which passes the bolt p which is secured to the socket m and the spiral spring 0 surrounds the bolt p and is interposed between the plate and the socket. The strap extends from each end of the plate at over the bolster it and'is provided with a buckle j.

In using my device, it is strapped on the forward or rear axle or both, one device on each side of the center in the rear and the double device shown in Fig. 1 in the front. When the upward rebound of the spring takes place, the motion is transferred through the strap and thence to the platesd and 'n which compress their springs.

The device is simple and easily applied and all the stress is taken by the spiral spring on compression.

1. A shock absorber-for vehicles comprising a plate disposed at right angles to the axle'o'f a wagon, a spring interposed be-.

tween the axle and the plate at their intersecting point and a substantially triangular member astride the bow spring of the axle and having its divergent ends connected to.

the ends of said plate whereby a slight arcuate movement on said plate is permitted.

2. A shock absorber for vehicles comprising an.. elongated plate adapted to bear against the under side of an axle and extending parallel therewith, spaced bolts depending from and rigidly secured to the plate, a coiled spring upon each bolt, a plate upon each bolt disposed at'right angles to said elongated plate and adapted to support the spring against said elongated plate, and angular yokes having their divergent ends connected to said second-named plates and having their apices adapted to rest over a bow spring-mounted on the axle.

.3. A shock absorber for vehicles com rising an elongated plate adapted to bear against the under side of an axle and extending parallel therewith, spaced bolts deits central portion extending over a bow pending from and rigidly secured to the spring on the axle. plate, a coiled spring upon each bolt, :1 plate In Witness whereof I have hereunto set my upon each bolt disposed at right angles to hand this 29th day of January, 1910.

said elongated plate and adapted to support ARTHUR L. MITCHELL. the spring against said elongated plate, and Witnesses:

an adjustable stra having its ends fastened S. W. BATES,

to the ends of sai second plate and having ELEANOR W. DENNIS.
